DESCRIPTION:Cycling has gained attractiveness in Germany in recent years\,
  particularly in urban areas. According to the ‘Mobility in Germany’ s
 urvey\, in major cities\, the share of persons using the bicycle at least 
 once a month rose from 51 to 53 percent between 2017 and 2023 (infas et al
 . 2025). At the same time\, residents in large cities and metropolises in 
 particular suffer from high heat stress in the summer\, as densely built-u
 p urban areas heat up particularly strongly during the day and hardly cool
  down at night. Consequently\, so-called heat days—days with temperature
 s of 30 degrees Celsius and above—occur significantly more frequently in
  large cities than the German average (UBA 2024).\nResearch shows that sea
 sonal fluctuations are more pronounced for cycling than for other modes of
  transport (Nobis 2019). Several studies have found that\, when it comes t
 o heat\, cycling rates increase up to a certain optimal temperature\, whic
 h may vary depending on the city or region. Once this temperature is excee
 ded\, however\, bicycle use declines again (Miranda-Moreno & Nosal 2011). 
 Several cyclists report switching to the car in order to avoid extreme hea
 t stress when cycling (Burghard et al. 2025). This means\, heat can hinder
  the transition to sustainable urban mobility.\nIn the ‘Heat Bike’ pro
 ject we investigate the influence of heat on cycling. For this\, we analys
 e data from shared bikes and bicycle traffic counters for German cities in
  order to determine whether bicycle use declines in hot days. Additionally
 \, we conduct a case study in Karlsruhe to explore how cyclists adapt to h
 ot weather. Based on this\, we analyse and develop strategies and solution
 s for cycling in extreme heat at the municipal level and assess their effe
 ctiveness.\nIn this contribution we will present first results and discuss
  the next steps in the project.
